To all whom it may concern:

Be it known that I, PBJLIP W. a citizen of the United States, residmg at Evanston, in the county 'of Cook and `State of Illinois, have invented new and useful Improvements in Ainticreepers for Rails, of which the following is a full, clear, concise, andexact description, reference being had to theaccompanying drawing, forming a part of this specification.I

My invention relates to an anti-creeping device for railway rails.

Among the objects of my invention I aim to provide an improved rail anchor which will effectively grip the rail when applied thereto and which will not loosen or relax its grip thereon when the pm between the anti-creeper and the tie is relaxed; which has a minimum of friction between the interlocking parts of the anti-creeper and a maximum of friction between said parts and the rail base gripped thereby; which has a. comparatively large angle of sliding engagement for the relatively movable parts of the anti-Creeper to provide for a take up, whereby the anticreeper may be applied to rails which vary m width, and which has parts that are positively locked against a movement which would tend to loosen their 3o grip on the rail base, and yet which may be disengaged when desired without breaking or mutilating the locking means.

The rail anchors shown in the accompanying illustrate two ents of the invention. Other embodiments may, of

course, be devised.

The views of the drawings are as follows: Figure 1 is a top plan view of a preferred form of rail anchor, the outline of the rail .sobeingshownindottedlin Fig.2isau end' elevation thereof. a Vportion of the rail being shown in elevation. Fig is an elevation partly'in section, taken onthe line3.3ofFig. 1. Figs.4,5and6are respectively a plan view and elevation and partial sectional elevation of a modified form of rail anchor.

The anti-creeper or rail4 anchor shown in Figs 1, 2 and 3 comprises two relatively movable members positive engagement with. each'v along a line somewhat diagonal `threspect to the length of the rail. The larger of the two members l may be called the clip and the smaller of the two members 2 may be called the mate. The clip l is provided with a rail-gripping jaw 3 which grips one side of the rail base, and the mate 2 is provided with a rail-gripping jaw 4 which grips the other side of the rail base. Either or both jaws may be reinforced by suitable Bauges, if desired.

The clip l is provided with an under-cut engaging wall 5, along which a correspond` 'mg under-cut engaging wall 6 on the mate 2 is adapted to slide when the parts are being assembled, and against which said wall 6 abuts firmly when the parts have been driven to their position of final engagement with each other and with the rail base. The mate 2 is received loosely within an outer jaw 7 on the clip l, said jaw also being' suitably reinforced. The clip and the mate as will be seen, have an interlocking wedgiug engagement beneath the rail base by virtue of the diagonally arranged under-cnt walls, consequently, when the parts are as-- sembled loosely on the rail base, and the mate is slid along the rail base within the jaw 7, it is apparent that the mate as a whole moves inward toward the center of the rail until the rail base is gripped between the opposite jaws 3 and 4. The mate is driven into its final position of firm wedging engagement by hammer blows directed preferably against the outer end thereof which is reinforced by a suitable flange 8 adapted to withstand said blows. The clip is provided with a. downwardly extending tie-abutting tongue or flange 9. and accordingly is driven firmly against the side of the tie at the same time that the mate is being driven into final position, as the hammer blows against the mate are directedtoward the tie.

The mate is provided with a plurality of small bosses or proiections 10 which are illustrated as being circular but which may have any desired conliguration. When the mate is beim! driven into the clip. these project-ions slide freely along beneath the relatively thin wall 11 in which the iaw 7 terminates. After the mate hns been driven toward the tie as far as possible. the clip and the mate are then positively locked against a return relative movement by bending llc-wn portions of the thin wall 'or die phi-agili il. the clip being constructed prefv er-.iblv or' malleable iron. In bending down the metal it is not neceiry'that the oper- 5 ntor know just where the are located, as all that ,is necessary is to direct a few hammer blows bacl; and forth along the Wall 1l. whereupon whatever portions thereof Vhappen to span two of the bosses 10, will be m deflected inwardly. B v providing a plurality of bosses an inexperienced or careless operator stands more chance of bending the metal at the right place than might otherwisehe the ease. YFurthermore, fthe metal 5 is deflected immediately behind morexan one boss, as in Fig. 3, for example, the seem'- o -t-he locking varrangement is corresppn'dingly increased.

-lt is tobe noted that although the mate is entirely incled by the jaw 7, said `jana"` performs no direct function in mahxtainng'thejparts in ment. asfsaid ment takes n'pla-ce en- Vtirl'y beneath the rail base. is a rult there isno friction between said mate and sa'i'd jan' aside from a possibleslight friction Vlieviweienthe'tlzin Wall 11 and the bosses I0 the metalis bent. There is-g'reater of oourse,between the interlocking wallsi and V6, buteven this fricption is relatively slight compared with-the developed between thejaws Brand 4 and the opposite sides of the rail base, as said jaws have to be-snrrmg somewhat when they are applied, and hencethey grip the -Vgnilbase Yfirmly both aboveand below.; furdxermore, the bearing surface is of considerable area..

The angle made bythe engaging walls 5 40 and 6 with the longitudinal axis of the rail is relatively great, and consequently the effectire width of tberail anchor.; that is to say, the space between the jaws 33nd 4 may be vag'iedfconsderably by 45 in ont of the clip. Accordingly, I am to. applythe rail anchor to rails of 'thereby Proriding the necessary take np. In this Vconnection it noted that even if itisfpossible to mate anly'about half way into the clip, -aS shown in Fig-1, mail@ Aprovided'sfrthtihere are always one or f t-'wo beneath the Awall or diaphragmffll sin position to lock the to-` egether whenf the Wns bent in.

Tnesdmmgeief proviene/pesava ikg toniaintin flieparks of the ancher in'theinmost eve position, iswell YBjr positivelockseing mns which I- havefdescribed aboigthe advantages Vare attained in .a and practical manner. 1H the rail hacks up for any reason, the rail anchorfas Y awtliole withdraws with the tie, ifV the si rai] subsequently moves vforward again1 the to engage .some other part and lock thelsame againstmorement. In view of the Aunnecessarily extreme bending to which these tongues may be subjected, they are apt tobreahV oli', or theymay also be broken b v carele handling prior to the installation of the device. In the present instance, the thin waIl'Il, which I have provided, is well protected during ordinary' handling and requires only slight deflection; hence the liability of breakage is minimized. When said Wall is deflected it, is bent down into the space between two adjacent projections and the eect isthat of bendingJr the metal into a re in the coperating member. Accordingly, it is immaterial whether or not the 'projections actually project above the suraceor whether the intervening space is depteed below the surface of said member.

In order to unlock the parts where it is desired to remore the rail anchor. it is only necearv to'force a cold chisel or some blunt toolA beneath the depressed wall so as to tend to straighten out the same and thereby pertbe loosening and removal of said parts.

lInthe form of rail anchorshown in Figs.

4,'5 and 6, the main elements are substan Y tially the same as those previously described andthe same reference characters have been used to indicate corresponding parts The rear wall 12 of the mate is inclined some- :that imm front to rear, whereby 'the reinforcing flange 13 may be bent downward by hmmer blows to prevent a return movement of said mate after the parts have been as vsemhled, said flange being made suiciently henry so as to withstand the blows and providing a hammering surface.

It is apparent that.- While the lockingV feas .ture described above as one phase of my inv'iitiomis particularly adapted to theanti- Creepers illustrated, it. is also adapted to anti-creepers of radically different kinds Accordingly, I do not limit myself to its use in connection with the anti-Creepers shown. As far as certain other phases of my invention are concerned. it is apparent that they 1 may all be employed in various different rev lations. In generaLA therefore. I do not limit myself to the particular combinations of elements described and shown. but desire to cover within the scope of my invention, suitable equivalent means for accomplishing the desired result wherever said means fall within the scope of the appended claims` What I claim as new and desire to secure by Letters Patent of the United States is 1 An anti-creeper for rails comprising a plurality of relatively movable members, one of said members haring a thin Wall adapted to be bent into a depression in another of said members so as to lock said two members against movement in one direction, said wall' extending in the direction of said relative movement whereby it may be deected in any one of a number of relative vpositions to eiect said locking.

2, A n anti-creeper for rails comprising a plurality of members one of which is provided with a projection and another of which is provided with a thin wall adjacent to said projection, whereby said wall may be deflected behimi said projection at any one of a number of intermediate points thereon to lock said members against movement in whatever position they may ame- 3. An anticreeper for rails comprising a plurality of movable parts, a plurality of projections carried by one of said parts and a thin wall carried by another of said parts, said thin Wall arranged to extend over Said projections whereby it may be bent down between two or more of said projecv tions to lock the parts against relative movement.

4, An anticreeper comprising two relatively movable members each having a jaw adapted to grip one side of a rail base, one of said members a plurality of ridges and the other of said members having a diaphragm adjacent to said ridges and spanning the same, whereby it may be deflected into the space between said ridges.

5. An anti-Creeper comprising two relatively movable members each having a jaw arrangedtogriponesideofa railbasewhen the parts are aemliled, one of said members having a tie-abutting flange and having a thin diaphragm adapted to be bent at some intermediate point so as to obstruct the movement of the other of said members 6. An anticreeper comprising two parts interlocking wedging engagement beneath the rail base, one of said parts having a thin Wall adapted to be deflected into a recess in the other of said parts 7. A rail anchor consisting of two parts having relative movement along a line somewhat diagonal with respect to the length of the rail, one of said parts having a jaw with inwhich the other of said parts is received loosely, said jaw terminating in a thin wall which is adapted to be deflected so as to ob struct themovement of said other part within said jaw.

8. A rail anchor consisting of two parts having abutting faces beneath the rail base which engage each other in a plane which intersects the rail base in a diagonal line, the length of said faces being suilicient to permit one of said parts to slide along the other a snflicient dist-ance to cause said parts to approach or recede from each other a considerable amount, whereby said rail an chor may be applied to rails of varying widths, one of said parts having a row of projections thereon, any one of which may act as a stop when engaged by a deflected portion on said other part.

9. An anti-creeper comprising a yoke and a Wedging member, said yoke having a railgripping jaw at one end and a larger jaw at the other end and having a diagonally arranged slot intermediate said jaws, said wedging member being received within said larger jaw and having a diagonally arranged rih received within said slot and hav ing also a rail-gripping jaw arranged opposite said first rail-gripping jaw= said wedging member being received loosely within said larger jaw, whereby the friction between said parts is confined mainly to the friction developed between said diagonal rib and the Wall of said slot, said larger jaw having reinforcing ribs connected by a Wall of thin metal which may be dellected to lock said other member within said jaw.
